WINDOW-VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 779,046, dated January3, 1905.

Application filed June 25, 1901. Serial No. 65,947; i

To all whom iihmay concern.-

Be it known that we, JOHN W. JONES and J o- SEPH RAMSEY, of Pittsburg,Allegheny county, Pennsylvania, have invented a new and usefulWindow-Ventilator, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which-- Figures 1 and 2 are front andrear elevations, respectively, of our improved windowventilator. Fig. 3is a vertical cross-section on the line III III of Fig. 1. Fig. 4 is adetail cross-section of the end strip, showing the method of insertion;and Fig. 5 is a partial inside elevation, partly broken away, showing acar-window arranged in accordance with our invention.

Our invention relates to that class of window ventilators whereininclined movable transparent slats are combined with a wire screen toform a cinder-proof and rain-proof window; and its object is to improvethe construction of such windows and provide means for regulating thedraft therethrough and for making the slats easily accessible forcleaning.

In the drawings, in which we show the window-ventilator arranged to beinserted beneath a window in a Pullman car, 2 9 represent the top andbottom rails, and 3 and 4 the end rails, of the window-frame. The endrail 4 is made of two pieces with a beveled or inclined joint betweenthem, as shown at 5 in Fig. 4. The

top and bottom rails are beveled in the same direction, as shown in Fig.3, and the window may be put in place by inserting the removable piece 5of the end rail 4 in the sash-recess and then pushing the window forwardinto place, the inclined joint guiding it into position. The car-window17 is then lowered, thus holding the screen-window in position. At itscenter the frame is provided with a central dividing-strip 6, and therear of the frame is composed of a shallow box 7 also having adividing-strip 8 at its center. Screens 9 9, of Wire-gauze or similarmaterial, are secured in the rear portion of the frame and form the rearface of the window, while transparent slats 10 are pivoted within theframe, so as to form the front face of the Window. These slats arepreferably slid into grooved levers 11, which are pivoted to the endrails 3 4 and the central vertical dividing-strip 6. The levers on thecentral dividing-strip are provided with projecting lugs 12, which arepivoted to a vertical connecting-bar 13, fitting between thedividing-strips 6 and 8. The connectingbar is provided with a pin 14,projecting through the strip 8, to which is pivoted a handle 15, havingapawl extension 16, adapted to engage ratchet-teeth secured to a slottedcasting fastened to the inner face of the dividingstrip 8.

In the operation of the window-ventilator it is securedbelow theordinary car-window, as above described, with the transparent slats onthe outside. The passenger may adjust the spaces between the transparentglass slats by means of the handle or may close them altogether, ifdesired, and the slats may be moved into different positions, varyingfrom a horizontal position to that in which they are in contact witheach other.

The advantages of our invention result from the pivoting of thetransparent slats in connection with the wire screen, since this enablesthe amount of draft to be regulated as desired and also enables theslats to be moved into horizontal position, where they can be easilycleaned. The dificulty with prior windows of this kind, which werepractically inaccessible for cleaning, is thus overcome, while at thesame time the amount of entering air may be regulated.

' We claim- 1. A window-ventilatorcomprisingaframe, a series of,transparent horizontal slats pivotally mounted in the sides of the frameand forming the outer face of the window, a wire screen attached to theframe and forming the inner face of the window, means for actuating saidslats situate in the frame between the slats and the screen, andoperating connections extending from said actuating means through theinner face of the window; substantially as described.

2. A window-ventilator comprising a frame. a series of transparenthorizontal slats pivotally mounted in the sides of the frame and formingthe outer face of the window, a wire screen attached to the frame andforming the I pivoted to each side of said upright andeach having arearwardly-extending arm, an actu- I the' inner faceof the window, andcatch mech anism arranged to engage said connections so as to hold theslats in adjusted position; substantially as described.

3. A window-ventilator having end rails and a central dividing-strip,two series of exterior transparent slats pivotally mounted between thedividing-strip and the end rails, an interior screen,and connectionsextending from the two series of slats to a common tiltinghandle on theinside of the screen; substantially as described. 4. A window-ventilatorhaving end rails and a central dividing-strip, two series of exteriortransparent slats pivotally mounted between the dividing-strip and theend rails, an interior screen, connections extending from the two seriesof slats to a common tilting-handle on the inside of the screen, andcatch mechanism to hold the slats in adjusted position; substantially asdescribed.

5. In a window-ventilator, a casing having a central upright therein. aseries of hangers ating-bar pivotally connected to the said arms or eachof the hangers, a series of hangers pivoted to' the side rails of saidcasing, with a series of slats received within the first and secondmentioned series of hangers, an arm" rigidly secured to saidactuating-bar, a toothed rack having a slot therein for receiving saidarm, and an operating-handle pivoted to said arm and carrying aprojection to engage said rack, substantially as described.

i 6. In a windoweventilator, a casing having acentral upright, series ofhangers pivoted on each side of the upright, an actuating-bar parentslats arranged within the hangers, a screen secured to the inner face ofthe casing;

having said hangers pivoted to its sides, tra'ns- 1 I 45- and carrying aslotted rack, an arm rigidly?"- secured to the actuating-bar andextending'f through the rack, and means pivoted'to'the arm and adaptedfor engagement with said rack'whereby the actuating-bar may be locked.

In testimony whereof We have hereunto set our hands. I
